Zvisere zveTekinoroji Zvinodikanwa zveCyanidation Goridhe Kubviswa kubva kuGoridhe Ores

Kubvisa goridhe recyanidation inzira inoshandisa cyanide senzira yekuburitsa goridhe. Nekuda kwetekinoroji yayo yakakura, kukurumidza kwayo kuburitsa goridhe, uye kugona kwayo kuchinjika kumatombo, nzira yekubvisa goridhe iri ichiri imwe yenzira huru dzekugadzira goridhe nanhasi. Munguva yekubvisa goridhe, zvakakosha kudzora zvese zvine chekuita netekinoroji kuti uve nechokwadi chekuti hupfumi hwadzoka zvakanaka. Chinyorwa chino chichakuzivisa nezvezvinodiwa zvisere zvetekinoroji zvekubvisa goridhe recyanidation kubva mumatombo egoridhe.

1. Aeration uye Cyanide Addition

Cyanide inowedzerwa kune slurry mushure mekukuya kunyungudutsa goridhe, kugadzira simbi complexes. Maitiro ekuita ndeaya anotevera: [Reaction formula inofanira kuiswa pano kana iripo]. Sezvinoonekwa kubva muequation, okisijeni inodiwa panguva yekubuda kwegoridhe. Naizvozvo, mukugadzirwa kwemaindasitiri, mweya unounzwa mutangi reLeaching. Iyo aeration pressure inowanzotenderedza 1 kg, uye mwero weaeration unodarika 0.002 m³ paminiti pa cubic mita ye slurry.

2. Kuwedzera kweProtective Alkali

Kuti uchengetedze huwandu hwe cyanide mu slurry, kudzivirira kusvibiswa kwezvakatipoteredza, uye kudzivirira chizvarwa uye kurasikirwa kwechepfu hydrogen cyanide (HCN) gasi, alkali inofanirwa kuwedzerwa kune leaching tank. Izvi zvinoita kuti slurry irambe iine pH yakakosha (10.5 - 11). Mukugadzirwa kwemaindasitiri, lime kana lime mukaka unowanzoshandiswa, uye dzimwe nguva NaOH inowedzerwa kuti igadziriswe.

3. Kuchengeta Slurry muNyika Yakamiswa

Iyo cyanidation yegoridhe yekubvisa maitiro ine chaiwo zvinodiwa pakuita kweleaching (adsorption) agitation tank. Pasi pemamiriro ekushandiswa kwesimba rakaderera, zvimedu zvegoridhe zvakasunungurwa kana kuti zvakafumura nzvimbo mu slurry hazvifanirwe kuisa mutangi. Iyo slurry, cyanide, lime, uye mhepo inofanira kunyatsosanganiswa uye yakaturikwa mutangi. Iyo slurry yekumisikidza inofanirwa kuve yakafanana pamativi ese etangi, pasina stratification pakadzika kwetangi, uye saizi yekugovera kunofanirwa kuve yakaenzana.

4. Kuchengeta Yakakodzera Slurry Concentration

Kana iyo density yegoridhe ore iri cyanided kubva pa2.65 kusvika 2.8. iyo general leaching slurry concentration ndeye 40 - 45%. Kana iyo density ye flotation concentrate iri 3 - 3.5. iyo general leaching concentration ndeye 30 - 40%. Iko kunaka kwezvinhu kunowanzoita zvekuti 80 - 95% yayo inopfuura ne200 - mesh sieve. Maitiro ekugadzira anoratidza kuti zvinhu zvakasiyana uye mamiriro ekugadzira anoda akasiyana agitation matangi.

5. Kuderedza Kupfeka uye Noise yeZvikamu Zvinofamba

Kuti uderedze kupfekedzwa kweagitator uye kuwedzera hupenyu hwayo hwesevhisi, akawanda mapellers mukugadzirwa kwemaindasitiri ane rubber - akaiswa mutsetse. Chishandiso chekufambisa chinofanirwa kunyatsogadziriswa kuti ive nechokwadi chekufambisa kwepamusoro uye ruzha rwakaderera.

6. Kuderedza Carbon Wear

Mukuita kweCarbon - in - pulp, kabhoni inowedzerwa mutangi readsorption kuti inyudze goridhe rakachekwa. Kana simba readsorption retangi readsorption rakanyanya kusimba, kabhoni ichakuyiwa yorasika; kana isina simba, sedimentation ichaitika. Nokudaro, panguva yekuchengetedza slurry iri mumamiriro ekumira, kune rumwe rutivi, carbon yakasimba inofanira kusarudzwa kuti ishandiswe, uye kune rumwe rutivi, kumhanya kwekutenderera kweimpeller kunofanira kuderedzwa kuderedza kurasikirwa kwekabhoni uye simba rekupinda retangi readsorption.

7. Kusarudza Chikero Chakakodzera

Parizvino, kugona kugadzirisa kwezvakajairwa cyanidation zvidyarwa kubva kune akati wandei kusvika makumi ezviuru zvematani pazuva. Iyo yakakura chiyero, iyo yakawanda ivhu, yakakura - saizi yemidziyo, uye mari yepamusoro inodiwa. Migodhi inofanirwa kuona chiyero chakakodzera chechirimwa zvichienderana nemamiriro chaiwo.

8. Kuderedza Equipment Weight uye Investment

Paunenge uchisarudza tangi inokonzeresa, inofanirwa kunyatsoshanda uye kuchengetedza simba pakudonha. Panguva imwecheteyo, mudziyo wekutapurirana unofanirwa kutora nzvimbo shoma, uye midziyo inofanirwa kuve yakareruka. Kamwe chiyero, slurry concentration, uye leaching nguva yakatemwa, huwandu hwematangi hunogona kuziviswa. Nekudaro, saizi yetangi yekushungurudza inofanira kunge yakakodzera chiyero. Semuenzaniso, kana 500 - t / d cyanidation chirimwa ichiri kushandisa φ3.5 × 3.5 m agitation tank, mimwe michina ichadikanwa, kuwedzera mari. Naizvozvo, chete kana midziyo yakareruka uye chiyero chakakodzera ndipo iyo yekuvaka yebhizinesi inogona kuderedzwa.

Izvi ndizvo zvisere zvinodiwa zvetekinoroji pamiti yegoridhe yecyanidation. Varidzi vemigodhi vanofanirwa kunyatso kudzora maitiro ese ekugadzira mukugadzirwa chaiko uye kutarisa akasiyana paramita munguva chaiyo yekudzivirira kurasikirwa kwehupfumi kunokonzerwa nekuita zvisina kunaka. Varidzi vemigodhi vanogona zvakare kubvunza vagadziri vane hunyanzvi hwekusarudza chirimwa. Izvo zvakakosha kuita ore-yekupfekedza bvunzo pachine nguva uye kugadzira hurongwa hwekusarudza chirimwa zvichienderana nemhedzisiro yebvunzo.
